This Text found you at the origin Website from GitKraken https://www.gitkraken.com/, i have build a Pisi Package from it and you could test it now.
Note this package needs gconf as Runtime Dependency:
You must add the contrib Repo in Pisi Linux 2.0 and type
sudo pisi em gconf
after it you can install the GitKraken package
Have Fun to test it
